Abstract

Some embodiments provided rotor assemblies, comprising: a rotor core barrel comprising a wall extending, and at least two compression bridges each formed in the wall proximate one of the lateral ends and separated by a distance; an array of a plurality of magnets positioned on and spaced along the wall between the compression bridges and about a circumference of the rotor core barrel; and one or more pre-stress wraps wrapped over the plurality of magnets and about the rotor core barrel along at least a portion of a length of the rotor core barrel between the compression bridges, wherein the compression bridges enable radial compression deflection, induced by radial compression of the rotor core barrel by the one or more pre-stress wraps, of the wall of the rotor core barrel at the compression bridges relative to the wall of the rotor core barrel proximate the lateral ends.

Description

BACKGROUND[0001]1. Field of the Invention[0002]The present invention relates generally to rotors.[0003]2. Discussion of the Related Art[0004]Many different types of machines incorporate magnetic rotors. The use of magnetic rotors extends to numerous different applications. Rotor stresses resulting from centrifugal force can, however, limit the speed and power density of motors, generators and other machinery incorporating rotors.SUMMARY OF THE INVENTION[0005]Several embodiments of the invention advantageously address the needs above as well as other needs by providing rotor assemblies. In some embodiments, a rotor assembly comprises: a rotor core barrel comprising a wall extending between lateral ends, and at least two compression bridges each formed in the wall proximate one of the lateral ends and separated by a distance; an array of a plurality of magnets positioned on and spaced along the wall between the compression bridges and about a circumference of the rotor core barrel; an...
